What is Viridis Agent Fleet MCP?
Viridis Agent Fleet provides deterministic, auditable MCP agents for identity, escrow, metering, and verifiable ecological or energy-related services.
Summary generated from the project's README
About Viridis Agent Fleet MCP server
The subscriptions server provides a fleet of deterministic and auditable MCP agents designed for the agent economy. These agents handle critical functions such as identity, escrow, metering, arbitration, and notary services. Developers can run these agents locally using Python and stdio MCP, or they can connect to a managed hosted service. The hosted version includes Viridis-signed receipts, a notary chain, and maintained rule packs for tax and GHG factors.
This system is built for users working in conservation, energy, and regulatory compliance. While the core agent logic is open-source and can be self-hosted for free, the hosted fleet offers managed payments, seats, and service level agreements. The free tier allows for 10 calls per day per service, though the fundamental rails for identity and escrow remain free forever. Every result is content-addressed to ensure anyone can re-verify the output.
What you can do with it
- 1Manage financial settlement railsDevelopers can implement identity, escrow, and metering tools to create trust and settlement rails for agents.
- 2Perform regulatory and GHG accountingUsers can access specialized agents for GHG accounting, tax credits, and regulatory radar monitoring.

README
View on GitHubViridis Agent Fleet: open-source agents for the agent economy
Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger), a free conservation-valuation rail (eco-funding: ecological complexity with re-runnable receipts), and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.
Licensed Apache-2.0. Run any agent yourself, fork it, embed it.
Run an agent locally (free, forever)
pip install -r requirements-dev.txt
python3 agent-escrow-agent/adapters/mcp_server.py # stdio MCP
python3 run_fleet_tests.py # every agent's invariant tests
Or use the hosted fleet
https://mcp.viridisconservation.com runs all agents as one managed MCP service:
| Self-hosted (this repo) | Hosted by Viridis | |
|---|---|---|
| Agent logic & verification | ✅ identical | ✅ identical |
| Viridis-signed receipts & notary chain | – | ✅ |
| Shared trust/reputation network data | – | ✅ |
| Maintained rule packs (tax, GHG factors, regs) | snapshot | ✅ kept current |
| Payments (x402, card), seats, SLA | – | ✅ |
Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.
Registry servers with their own docs
Each registered MCP server has a README with its tools, inputs and outputs, an example, client config and pricing:

For agents
Agents and LLM tools can start from llms.txt, a generated index of every agent, and AGENTS.md, the rules for using and changing the fleet.
Part of the Viridis open-source commons
Building agents for conservation or energy work? VergeCommon and EnergyAI MCP also expose MCP tools, and ViridisOS serves its decision functions to agents over MCP.
This project is one of a connected set of open tools from Viridis. Each stands on its own; together they run from field evidence to checked decisions.
Conservation commons
- VergeCommon: community conservation co-ops with consent-based land mapping, field evidence and group decisions
- Dendritic Forest Management (DFM): compare forest-retention options around roads and waterways, with traceable inputs and portable reports
- Global Soil Intelligence Project (GSIP): contribute soil observations and explore open soil maps with explicit uncertainty
Verifiable science
- Viridis Canon: machine-checked Lean 4 mathematics for ecological decisions, with a DOI for every result
- ViridisOS: open reference runtime for DOI-backed decision modules and recomputable results
- Viridis Research: the nightly public research record, each claim labeled by what a verifier actually checked
- ProofLens: see what a Lean statement means before reading the proof
Agent tools
- Viridis Agent Fleet (this repository): open-source MCP agents with deterministic, auditable cores
- EnergyAI MCP: energy-planning estimates and incentive sources for AI agents

Boundary
This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.
